请问大家下面这段代码中setnamed命令中的几个分别代表什么意思啊？脚本运行的时候发现半径为0.25μm时可以正常运行，但为0.75μm的时候出现一个错误： '+&!;Jj,  
Warning: in run: there was no simulation data. The simulation failed to run. }y>/#]X  
Error:  Can not find result 'E' in the result provider 'field' #KUNZW  
代码如下： WU\Bs2  
radius = 1e-6*[0.25,0.75]; l3N '@GO  
for (i=1:length(radius)) { lK Ry4~O  
    setnamed("::model","radius",radius(i)); -[}AhNYK  
    run; HC!5AJ&+}v  
    E = getresult("field","E"); @Ta0v:Y  
    x = E.x; IE:;`e:\D  
    z = E.z; 0u}+n+\g  
    Ex = E.Ex; Y>2oU`ly,  
    image(x*1e6,z*1e6,pinch(real(Ex)),"x (um)","z (um)","Real(Ex) - "+num2str(radius(i)*1e6)+" um"); fA)4'7UT
